CAR-DOOR HASP.

Specification of Letters Patent.

Patented Nov. 18, 1913.

To all whom it may concern:

Be it known that we, JOHN T. KEMPER and CHARLES l/V. KEMPER, citizens of the United States, residing at Garberville, in the county of Humboldt and State of California, have invented new and useful Improvements in Car-Door Hasps, of which the following is a specification.

This invention relates to a car door hasp.

The object of the invention is to provide a simple, substantial and automatic door latch especially adapted for freight car doors, which will permit the door to be securely locked entirely closed, or partly open when ventilation is desired.

The invention consists of the parts and the construction and combination of parts as hereinafter more fully described and claimed, having reference to the accompanying drawings, in which Figure 1 is a side elevation, showing the application of the invention. Fig. 2 is a section of the car door and frame, showing the position of the locking hasp. Fig. 3 is a perspective view of the hasp. Fig. 4 is a perspective view of the locking bolt.

Referring to the drawings: A indicates the main hasp plate, which is secured to the door 2 by a staple 3, or a similar device, which will permit a free swinging movement of the hasp plate with relation to the door. Slidablv and pivotally mounted on the plate A is a locking lever 4; the sliding and pivotal movement being produced by forming a slot 5 in the locking lever, and a similar slot 6 in the hasp plate, through which passes a pivot bolt 7. The lower portion of the hasp plate is also provided with a secondary oblong slot 8, the bottom portion of which is provided with locking serrations or teeth 9, and operable in unison with the oblong slot 8 is a similar slot 10, formed in the locking lever 4.

Suitably secured to the stationary door frame 11 is a locking bolt 12, which is provided with an angular perforated head member 13, a round shank portion 14, and an angular downwardly projecting lug 15. Extending at right angles to the V-shaped lug 15 are a pair of perforated projecting lug members 16, adapted to contact with the door frame. The lugs 16 are simply provided for the purpose of preventing any side-play or twisting of the locking bolt 12 with relation to the hasp plate A. The inner end of the bolt is provided with a locking nut 17, while screws 18 are provided for the purpose of securing the lugs 16 with relation to the door frame, thus securely holding the bolt in position.

In operation, when it is desired to lock the door it is first necessary to swing the locking lever 4 into the position indicated in Fig. 3, where the slots 8 and 10 register. The hasp plate A, together with the locking lever, is then swung into position with relation to the locking bolt until the perforated head 13 projects through the slot 10 in the locking lever; one of the serrations 9 will then register with the downwardly projecting V-shaped lug 15. The locking lever 4 at the same time registering with the round shank 14, may then be swung downwardly in the direction of arrow a about the pivot bolt 7 until the position shown in Fig. 1 is assumed. This brings the slot 10 into a vertical position with relation to the head 13 of the bolt, where the shoulder portions of the bolt engage with the side of the lever; thus preventing the removal of the hasp with relation to the bolt. The registry of one or another of the serrations 9 will correspondingly prevent any sliding movement of the door with relation to the stationary frame.

For the purpose of locking the lever against swinging movement about the shank portion 14 on the locking bolt, to release the hasp plate with relation to the bolt, we have shown the top portion of the locking member as being provided with a perforated lug 19, through which and the erforated head 13 a wire 20 may be passed The ends of the wire may then be twisted and sealed with a lead seal in the usual manner, thus preventing a swinging movement of the locking lever with relation to the bolt.

In some instances, the hasp plate may be locked in position by simply applying a padlock 21, as indicated in Fig. 2.

\Vhen it is desired to secure ventilation within the car, it can readily be seen that the door may be locked partly open; the open position of the door being regulated by bringing one or another of the serrations 9 into register with the downwardly projecting lug 15. A door hasp or latching device, constructed as here shown, while particularly adapted for sliding doors may be equally applicable to any door construction. The substantial construction, together with the adjustability and simplicity of operation, permits its application in many instances where sliding doors are not used.

The materials and finish of the several parts of the hasp are such as experience and judgment of the manufacturer may dietate.

We wish it understood that various changes in form, proportions and minor details of construction may be resorted to within the scope of the appended claims, and that we do not wish to limit ourselves to the specific design and construction here shown.

Having thus described our invention, what we claim and desire to secure by Letters Patent is:

1. In a door hasp, the combination of a hasp plate, a longitudinal slot formed in the plate, a pivot pin slidably mounted in said slot, a locking lever pivotally and slidably mounted on said pin, a secondary longitudinal slot formed on the hasp plate, serrations formed in the lower edge of the slot, a stationary locking bolt with which said slot is adapted to register, means on the bolt adapted to interlock with the serrations in the slot, and a slot on the locking lever adapted to be brought into locking engagement with the locking bolt.

2. In a door hasp, the combination of a hasp plate, a longitudinal slot formed in the plate, a pivot pin slidably mounted in said slot, a locking lever pivotally and slidably mounted on said pin, a secondary longitudinal slot formed on the hasp plate, serrations formed in the lower edge of the slot,

a stationary locking bolt with which said slot is adapted to register, means on the bolt adapted to interlock with the serrations in the slot, a slot on the locking lever adapted to be brought into locking engagement with the locking bolt, and means for looking the locking lever on the locking bolt.

3. In a door hasp, the combination of a hasp plate, a longitudinal slot formed in the plate, a pivot pin slidably mounted in said slot, a locking lever pivotally and slidably mounted on said pin, a secondary longitudinal slot formed on the hasp plate, serrations formed in the lower edge of the slot,

a stationary locking bolt with which said slot is adapted to register, a downwardly extending lug on the bolt adapted to interlock with one or another of the serrations formed in the slot, a head formed on the bolt, a slot in the locking lever adapted to be brought into locking engagement with the head on the bolt, and means for locking the lever against disengagement with the head of the bolt.

In testimony whereof we have hereunto 1 set our hands in the presence of two subscribing witnesses,

JOHN T. KEMPER. CHARLES W. KEMPER,
